Gurney-Integrated CPR Piston Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CPR devices are not compatible with gurneys, making it difficult to provide automated chest compressions while transporting and immobilizing patients, especially over rugged terrain or stairs.
Innovation Solution
A piston-based chest compression device is secured to a gurney, allowing for mechanical CPR by compressing the patient's chest against the gurney deck, while the gurney's side rails provide support and stability for the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional CPR devices are used, then chest compression can be provided, but the device cannot be effectively combined with gurneys for patient transport
Solution Approach 1:
The CPR device is designed with universal mounting capabilities that allow it to be integrated with gurney side rails, enabling the same device to function both as a standalone CPR machine and as a gurney-integrated system. The adjustable arms and mounting mechanisms provide multi-functionality across different usage scenarios.
Solution Approach 2:
The CPR device is divided into separable components including adjustable arms, mounting brackets, and the main compression unit. This segmentation allows the device to be easily attached to and detached from gurneys without permanent modification to either component, reducing integration complexity while maintaining compatibility.
2Productivity
If mechanical CPR device is integrated with gurney, then simultaneous transport and CPR are enabled, but device structure becomes more complex
Solution Approach 1:
The CPR device and gurney are merged into a single integrated system where the CPR mechanism is mounted on the gurney frame. This combining allows simultaneous patient transport and mechanical CPR without requiring separate equipment, improving productivity while using standardized components to minimize added complexity.
3Reliability
If piston-based compression device is used, then effective chest compression is achieved, but the device requires stable support structure
Solution Approach 1:
The piston-based compression device is mounted on the gurney side rails at a height and position that provides optimal mechanical advantage and stability. The support structure is designed to create an equipotential mounting configuration where the compression force is efficiently transmitted to the patient's chest without requiring additional complex stabilization mechanisms.
